# This is the "base" image workflow.
# While it has a bunch of intermediate stages, it "exports" a couple
# stages for consumption.
# - python-base: A basic stage, with basic deps, Python, and a venv.
# - ingestion-base-slim: Currently the same as base-empty.
# - ingestion-base-full: Adds a JRE and Oracle client.
